Abstract

L'invention concerne un procédé pour commander une transmission de paquets de données entre un émetteur et un récepteur d'un réseau de communications de diffusion, selon lequel la transmission d'un paquet de données est réalisé de manière commandée, en fonction d'une valeur de qualité de service associée. Un des paquets de données envoyé est ensuite associé côté réseau fixe à une valeur temporelle synchronisée. La commande de la transmission de paquets de données se produit en fonction de la valeur temporelle associée.
